Cloudflare identified 2,000 bugs across its critical-path systems, including 400 rated high or critical, with a false-positive rate the company said it considered better than that of human testers. At one unnamed partner bank, the model was credited with helping detect and prevent a fraudulent $1.5 million wire transfer initiated after a customer\u2019s email account was compromised and followed up with spoofed phone calls.<\/p>\n<p>External evaluations cited in the update tracked with the results Anthropic released. The United Kingdom\u2019s AI Security Institute found that Mythos Preview was the first model to solve both of its cyber ranges \u2014 simulations of multistep cyberattacks \u2014 from end to end. Mozilla said it found and fixed 271 vulnerabilities in Firefox 150 while testing the model, more than 10 times the number found in Firefox 148 using an earlier Anthropic model. AI-powered security platform XBOW called the model a significant step up over existing systems on its web exploit benchmark.<\/p>\n<p>Anthropic also used Mythos to scan more than 1,000 open-source projects. The model has flagged 23,019 potential vulnerabilities, 6,202 of them estimated as high or critical. Of 1,752 high- or critical-rated findings reviewed by six independent security research firms or by Anthropic itself, over 90% were confirmed as valid, and over 62%&#8230;<\/p>\n<p><a href=\"https:\/\/cyberscoop.com\/anthropic-mythos-software-flaws-glasswing\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Anthropic: Mythos finds more than 10,000 software flaws in first month https:\/\/cyberscoop.com\/anthropic-mythos-software-flaws-glasswing\/ Publish Date: 2026-05-26&#8230;<\/p>\n","protected":false},"author":1,"featured_media":256066,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/cyberscoop.com\/wp-content\/uploads\/sites\/3\/2026\/05\/GettyImages-2276989325-1.jpg","fifu_image_alt":"","footnotes":""},"categories":[15],"tags":[26,24,31],"class_list":["post-256065","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cybersecurity","tag-ai","tag-cybersecurity","tag-exploit"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/256065"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=256065"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/256065\/revisions"}],"predecessor-version":[{"id":256067,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/256065\/revisions\/256067"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/256066"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=256065"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=256065"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=256065"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
